My invention relates to a turn indicator for a motor vehlcle, andcomprises a vert cal Vind cator stem or. stems rotatably mounted in thefront part of the vehicle,'h aving is i upper end a horizontalarmcarrying anindicator lamp normally indicating the direction parallel tothe longitudinal axis of the vehicle, and a hand lever or pedaloperatively connected to said indicator stem'or' stems for rotating thelatter in either direction through an angle'of 90, so thatthe indicatorlamp is turned to the right or left toindic'ate; the desired directionin which the driver' ntends to turn the vehicle.v

The object of myinvention isto devise a l novel turn indicatorfor a mO OVehicle which 7 operated. Y I V 1. i In the drawings, illustrating whatnowconsider the preferred "forms-off my invention: v r

Fig. 1 is a front view of a motor vehicle equipped with a deviceaccordingto 1n is simple in construction and can be readily Fig. 4 showsinsection'a modifiedformof mechanism for operatingthe indicator stem.Fig. 5 isa sectiontaken at right angle to Fig.4. j w p, Fig. 6shows insection anothermodification of the mechanismfor operating the indicatorrstems. i

I F'g. 7 is a pinionshown in Fig.;6.

In'carrylng. out my 111vntlQI1,;I provide a rotatable'verticalstempreferably on both? sides atthe front of the vehicle. Each stem 5projects upwardly "and at; itsfupper'end it is provided with an armlcarrying an, indicator consisting of alamp, Said indicator stems areprovided at lower ends .with gears and are connected means of a driving-5-0 chain'or a toothed rack to a toothedwheel Fig. 2 is a sectional viewshowing one'lform' toothed wheel 4 in either direction bothfin detailplaniview ofa rack andl; through an angle of"9'0, whereby indicating andthe latter is adapted t be partially ro tated in "either directionby"means of-a "pedal o'rxhand leverd The arrangementis such that} byactuating said hand lever or pedal 'each'indicatorstemds:rotated'through an angle 5 Of-QO ineither'directiori;sothatgthe lamp on the arm fixed on the sten1 '-maybe'turned i to indicate rightiturn or left-turd according tral'positio'nand indicate the'direction paral 'IeLt tHelOngitudinalaxisoftlievehicleflv Beferringtoi Figs. 21 arias, in the easel are mounted twotoothed'racks 2; 2f ra ing'w each other, which-ra'cks being 'normallypressed upwardly by springfs8,3"i Engaged and embraced bysaid-toothedracks 2', 2" is a toothed wheel rotjatably mtiunc donon ofthe walls'of thecajse fl." ""fIhe'toothed wheel 4. j has integral;therewith "a bevel-- gear which. 0

, engages with *another bevel gear 1 5 secured to'a sprocket wheel '62-On thej'lower end of" each, indicator stem-"9 is :lixed "a sprocketwheel i-Zwhich is "connected by means of an endless drivingchain 8-; ithe "latter being passed around the sprocketwheel 7,111.18

sprocket-wheel 6 and other sprocket wheel 7 i (not shown); "so that uponrotation of the dicato i stems 9 are "rotatedin the cor n transverse armcarrying an indicator lamp" 10 'adapted'to b,e'ign'ited-atnigh'tl a rFrom foregoing it be "seen that upon fdepressibnpf either one of thetoothed quently that; the "arms with the indicator lamps 10 are turnedto'the right or left 93 the direction in whichthe driver just intends toturn the vehicle. i

In the embodiment showlnin Figs. and '5 the toothed wheel 4" is adaptedto be retated in either directionby means ofa hand wheel; and isconnected to other'sprocket wheels 12 ,(only one thereof-being shown) bymeans, of an endless: driving'chain 13. Fixed we. so

e5 racks 2,12 the ,toothed wheel 4 is'rot'ated in the'eorresp'onding'direction, and conse- 95 leverll which isdirectly fi-Xedto the wheel 74". ,The'tlatter is constructed as a sprocket on the same axis of thesprocket wheel 12 is a bevel gear 15 which cooperates with a bevel gear16 fixed on the lower end of the indi cator stem 9. In thisconstruction, the in-' dicator lamps 10 are turned to the right or leftby pushing forward or pulling backward the hand lever 11, which movementbeing transmitted through the sprocket wheels 1, the chain 13, thesprocket wheel 12, bevel 10 gears and 16 to the indicator stem 9'carrying the lamp 10.

In the further modified form of embodiment shown in Figs. 6 and 7, thedriving chain 13 in the above mentioned embodiment 15 has been replacedby a toothed rack 17 In this case, there is preferably provided anantifriction roller 18 supporting the rack bar 17 and running on therail formed by the base plate of the gear case 1.

2o VVhilst in the drawings only .one indicator stem 9 is shown asconnected to the actuating means, it is preferred that in practice twosimilar indicatorstems 9, each carrying the lamp 10, are arranged onboth sides in the front part of the motor vehicle 19 as shown in Fig. 1.I j I As herebefore described, according to my invention, the driver mayeasily turn the indicator lamps 10 into a desired direction bymanipulating the hand lever or one of the toothed racks having pedalsand when the indicator lamps have finished their service each indicatorlamp is returned to its normal position indicating the directionparallel to the longitudinal axis of the vehicle by returning the {handlever or the pedal to its neutral or initial position.

What I claim is A motor vehicle traflic signal comprising a revolubleindicator stem having an indicator stem having an indicator device, atoothed wheel mounted for I'Ot2I-t10I1,-L pair of manually operableracks arranged on opposite sides of said toothed wheel and having meansto guide them vertically, springs to normally hold said racks inelevated position, disengaged from said toothed wheel, and powertransmission means connecting said toothed wheel and said signallingstem.

In testimony whereof I aflix ny signature.
